You appear to have major network connectivity problems.
Squid apparently has a sub-mode which is shifts to so you can get to
already-cached content even when the network underneath it is down or
falling apart.

The code in squid which says that is documented:

* This function is designed to serve a fairly specific purpose.
* Occasionally our vBNS-connected caches can talk to each other, but not
* the rest of the world. Here we try to detect frequent failures which
* make the cache unusable (e.g. DNS lookup and connect() failures). If
* the failure:success ratio goes above 1.0 then we go into "hit only"
* mode where we only return UDP_HIT or UDP_MISS_NOFETCH. Neighbors
* will only fetch HITs from us if they are using the ICP protocol. We
* stay in this mode for 5 minutes.
